Each Danfoss PSH scroll compressor is equipped
with two lift rings on the top shell. Always use
both these rings when lifting the compressor.
Use lifting equipment rated and certified for
the weight of the compressor. A spreader
bar rated for the weight of the compressor is
highly recommended to ensure a better load
distribution. The use of lifting hooks closed
with a clasp and certified to lift the weight of
the compressor is also highly recommended.
Always respect the appropriate rules concerning
lifting objects of the type and weight of these
compressors. Maintain the compressor in an
upright position during all handling manoeuvres
(maximum of 15° from vertical).
Never use only one lifting lug to lift the
compressor. The compressor is too heavy for the
single lug to handle, and the risk is run that the
lug could separate from the compressor with
extensive damage and possible personal injury
as a result.
Store the compressor between -35°C and 50°C,
not exposed to rain, corrosive or flammable
atmosphere.
When the compressor is mounted as part of
an installation, never use the lift rings on the
compressor to lift the installation. The risk is run
that the lugs could separate from the compressor
or that the compressor could separate from the
base frame with extensive damage and possible
personal injury as a result.
Never apply force to the terminal box with the
intention of moving the compressor, as the
force placed upon the terminal box can cause
extensive damage to both the box and the
components contained inside.
Compressor handling and
storage
Maximum inclination from the vertical plane
while operating must not exceed 3 degrees.
Compressors PSH019-039 come delivered with
four rubber mounting grommets and metal
sleeve liners that serve to isolate the compressor
from base frame. These grommets must always
be used to mount the compressor in a single
application. The grommets must be compressed
until contact between the flat washer and
the steel mounting sleeve is established. The
grommets attenuate to a great extent the
transmission of compressor vibrations to the base
frame.
The required bolt size for the PSH019-039
compressors is HM8-40. This bolt must be
tightened to a torque of 15Nm.
Compressor mounting
Currently PSH019-23-26-30-34-39 are only
qualified with even tandem combination. The
recommended tandem piping design is similar
to even tandem of SH090-105-120-140-161-184.
More details about PSH tandem configuration
and installation guideline, please refer to SH
parallel Application Guideline FRCC.PC.008.
(Note: The model reference relationship between
PSH and SH are: PSH019 refer to SH090, PSH023
refer to SH105, PSH026 refer to SH120, PSH030
refer to SH140, PSH034 refer to SH161, PSH039
